The seed vault at PlantBank is one of the most biodiverse places on the planet. It holds seed collections of many of the 25,000 plant species that occur in Australia. Most of the seeds are from New South Wales species, and some are rare and threatened in the wild.
By 2020, all New South Wales species will be represented either here or as living plants growing within the Australian Botanic Garden. The vault has the capacity to store this number of species many times over. It can also house large seed collections for use in the restoration of degraded habitats.
The success of conserving seeds for the long-term depends on the collection of good quality seed, correct preparation of the seed for storage and maintaining the collections in dry, cold conditions. The colder the storage temperature, the longer the seeds will last.
